Introduction
The solid substances existing in nature can be divided into two categories: crystalline and amorphous. The essential difference between crystalline and amorphous structures is how the atoms, ions, molecules, and other particles that make up the structures are arranged. Crystals are regularly arranged (long program), while the particles in amorphous substances are stacked together irregularly (short program) and are the closest to them. Throughout life, we often see the existence of many crystals in day-to-day objects, such as salt, snow, and minerals, to name a few. In the field of crystallography, researchers study the symmetry of crystal structures in order to perform data collection and categorize substances. What we are going to introduce today is the crystal structure arrangement, which can be covered crystal structure from several directions: First, the crystal structure laws Second, the influence of structural change on crystal generation Third, the properties of crystals
